Store DTI to file - Append not working with "Only csv"


Recommended Posts

Hi,

I'm trying to build a log for my system using the Store DTI to File function. This runs after the struct containing the date is inserted into row 0 of a table, which should be appended immediately to the log file. The writes are sufficiently spaced (~30 minutes) that the SD write interval isn't an issue.

I've found that when using option 2 "Only CSV" for the "Create CSV" input (F), the file is simply overwritten, and only ever contains 1 row. Option 1 "Create CSV  File (All - udtf,csv,csv.zip)" does append correctly.

In both cases "Append to File" (E) is set to 1 "Data will be appended to the file".

This looks like a bug to me, and combined with the missing documentation for those options, I've wasted a little more time than I'd like trying to figure that out. Option 1 is an acceptable workaround, so I don't need further support, but this should be fixed.

Dear Sandy,
For now you have to use "1" in "F" parameter in order to get the CSV you want. 

Note:
'Store DT To File' Ladder utility:

  • Parameter in
    • A, Data Table to store
    • B, Start row in store file
    • C, Target file name
    • D, Number of rows
    • E, Append to file (0 – Overwrite, 1 – Append)
    • F. Create CSV (0 - No CSV, 1 – All files, 2 – Only CSV, 3 – Only CSV.zip)
    • G, CSV file delimiter
       
  • Parameter out
    • H, status

We have also confirm this issue on one of the newly purchased  HMI/PLCs system using the Unilogic firmware 1.28.34 . 

We'll use the append option "1" (all files formats ) with the "Store DTI to..."  as a  work-around until new update is fixed. Thank you for posting.
